A'U-'TOMOBIE JACK AND BRAKE OPERATING DEVICE.

Application led October 12, 1925.v Serial No. 62,086.

`This invention relates to improvements in automobile jack and brake operating devices as described in our United States application Serial Number 757,941, filed December'24th, 1924, and allowed May 14th,' 1925, issued November 3, 1925, Patent No. 1,560,460, for automobile jack and brake operating devices, and the objects of the invention are to provide an effective, ldurable and simply constructed device for jacking an automobile or the like and operating the brakes, which can be readily fitted to carsI of different construct-ion without interfering therewith and whereby the wheels may be l5 jacked individually or collectively without moving from the drivers seat.v v i Further objects are to provide a device of this character in which the brakes are automatically applied to the wheels not being 20 jacked.

Still further objects are vto, provide jackoperating means so arranged with brake operating means for automobiles and the like that the jacks may be operated independently of theibrakes Vto jack one or all of the wheels and "whereby, in the operation of the jacking` means, the brakes are automatically operated to apply their brake to Y the wheels that are not being jacked.

Still further objects are to provide combined jack and brake operating means for automobiles and the like which can be operated independently or simultaneously from thedrivers seat.

Yet another object is to provide jack and brake operating means adapted to all makes of automobiles, low priced as well as high priced, and particularly designed to be economically operated and so constructed that. it will not be liable to get out of order and will at the same time effectively perform the various functions required. A

Another object isi to provide jack and brake operating means for cach Wheel of an automobile and the like which can be adapted to any type of car and which can be fitted at a price'within the reach of all automobile owners.

With the foregoing and other objects in view, the inventionconsists essentially in the combination with a vehicle .such as an automobile -fitted with jacks and .brakes for one or more of the wheels, of means operable from the drivers seat for separately operating and applying from the. same control .the jack in operating position,

the jacks and brakes, for applying the brakes to the wheels that are not being jacked and for applying the brakes in the ordmary way without interfering with the jacking means.

Referring now to the drawings, -in which like characters of reference indicate corresponding parts in each figure:

14, 15 and 16 desi ate the jacks, one for each wheel arrange adjacent thereto `on the' axles 17 and 18 of the car. The essential features of our invention are the means in -the form of liquid,air or the like, under pressure,vcontroll ed and operated from the drivers seat whereby these jacks are suitably operated at the will of the driver and whereby the brakes are suitably applied, also as desired by the driver. For thls purpose we provide an auxiliary tank 19 mounted on the inside of the dashboard 10, and a control box 20 mounted adjacent thereto. This control box forms an important feature -of our invention, and comprises, as more .Figure 12 in the'control box, are designed to register'with a series of spaced openings 31 and 32 in thevtop and bottom of the box While, when the valves are rotated, the passageways. 28 arranged at right an les to the passageways '27 will register wit a series of openings 33 andl 34 in the top and bottom e box respectively.- TheI openings 32V are each connected directly byA conduits 35-y with the brakes, while the openings 34 are connected through conduits 36 with the jacks for each. wheel. These conduits 35 and 36 are formed with branches 37 and'38 at their `upper ends which communicate with the triangular passageways 29 and 30 in the valves, which in turn communicate with the return conduits 39. and 40 leading toy themain ref turn conduit. 41 see Figure 17) `which is connected to the reservoir or tank 19;

. Communicating with the-series of open- 1ngs`31 and l.33 in the top of the .member 20 and, for, supplying the `operating medium in' the form of oil in the present texam le o our lnvention, are formed longitudinal y extending channels 42 and 43 communieating,`

on op -osite 4sides of the box with conduits 44 an 45 connected attheir other ends to the-pump 47 being connected to the tank 19 bya branch conduit 48' (see ,Figure 1). The

conduits and'48 are providedwith ball check valves 49 and 50 lso 4that when the pump 47 is operated the liquid or'othervsuit-V able operating .medium in the tank 19 will be drawn therefrom through the conduit 48.

box, the

and, on the pump 47 being -further operated,

will be forced under pressure through the conduit 45 into the Lcontrol box 20 into'the channel 43 and thence, as the valves are op- 'erated, through the openings'33, 28 and 34, under pressure, through conduit 36 to the jacks, returning through branch 38- ofsa'id conduit intothe passageway 30 in the valves and on the valve being further operated back through conduits 40 and the main conduit 41 to the tank 19.

From 'the foregoing it w1ll be readily seen that, tak-ing for instance the left hand front wheel 5 1 which it is proposed to jack, the driver of the car will first-rotate the valve 23 `until the passageway y28 therein registers with the openings 33 and 34 in the control I assag'eway-27 for the brakes be ing closed) and the branch 37 of the conduit 35 registering with thereturn passageway 29 in the valve. The pump 47 is then operated causing the operating medium, in the presentinstance oil, to be-drawn from the tank 19 through the conduit 48 and deliv-4 ered'u'nder pressure', through the conduit 45 and the channel 43 in the control box to the openings 33, passageways 28. and conduit 36, to the jack 16 where, as also hereinafter more fully described, it causes the jack to assume a'- vertical position, as illustrated in Figure 6, lifting the wheel from the ground.v Referring now to Figure 11, the channel 43 is co'nnected by afcross channel 52 to the channel- 42 so thatjwhen the operating medium is delivered to tlie channel 43 it will also be delivered to the channel 42 andfwill vbe available to operatev the brakes through openings 31 on those wheels which are not being jacked.' The operation of the brakes i's similar to that of the jacks, the pump 46 being operated 'to discharge the liquid under pressure' through -conduit 44 into the channel 42 in the control member 20, and thence through the openings 31, passagewa s 27 and 32, conduits 35, direct to the bra es, the return being through the conduit 35, through the i channel 42 and thence through -conduit 44 back to the pump 46.

Circulation in the Aconduit and control system is provided for b pressure generating means in the-form o pumps 46 and 47,

las illustrated in Figurel, both ofwhich are o erable from the driver s seat. The pump the floor of the automoblle and whereby, oni

it bein moved backwardly. and forwardlyl as prevlously described, the operating medium for the jacks isgdrawn through conduit 48 from the tank 19 and forced under pressure'backthrough the conduit 45. into' the control box. The piston' rod of the pump 46 is connected to 'a cross-bar 57 pivotally mounted at 58 and connected at its other end 59 to a rod 60 in turn connected at 61 to the foot-operated pedal member 62 protruding through the footboard 11 so that when the pedal 62 is pressed by the operator the piston rod of the pump will be operated to generate pressure.

It will be noted that there is no direct con- .connecting channel 52 into the channel 42 and thence back through the conduit 44 to replenish the pump 46, there being accordingly always a sutlicient supply of the operating medium in this pump so that when it is operated by the pedal member 62 the fluid l uor air will be immediately subjected to pressure and delivered to the control box.

On the other hand, when it is desired to only apply'the brakes, the foot pedal 62 is operated to operate the pump 46, causing the fluid to be delivered under pressurethrough the conduit 44 to the control box and into the channel 42 therein and thence through the openings 31 and the passageways 27 in the valves to the brakes. It will thus be seen that the brakes can be operated completely apart from the jacks and also that on the jacks beingoperated the wheels whichfare not jacked will automatically have the brakes applied.

Referring again to Figure 11, it will be noted that the valves 23, 24, 25 and 26 are spring-actuated, their protruding ends being provided with coil springs 63 wound thereon and securely vheld in tensioning position by the washers 64 and lock nuts 65, while the other ends are 'formed with suitable handle means which extend through the instrument board to be readily operable from the drivers seat. The control box is also provided with a pressure gauge 67 adapted to indi- `cate at all times pressure in the system.

Arranged in the control box 20 is a pressure release valve 68 similar in construction to the valves 23, 24, 25 and 26, except that there' is only one passageway 69 therethrough adapted to register with the single passageways 7 0 and 71 (see Figures 11 and 12) in the top and bottom of the box respectively. This 'release valve is connected through the passage 71 to the main return line or conduit 41 (see Figure 17) which in turn is connected to each-of the valves 23, 24, 25 and 26 by branches 40 forthe 'jacks and branches 39 for the brakes. This release valve is springactuated also, similar to the other control valves and when rotated so that the passageway 69 will register with the passageways proper registerl ofthe several open-v pivotally All the valves are provided with izontal position, and in which is a slidably mounted plunger member78 provided with a foot 79. In normal position, as illustrated in Figure 3, the member 76 is ina horizontal position and when op/erated automatically assumes a vertical position to raise the wheel,- as indicated in Figures 3, 4 and 6. For operating the member 76 the pressureoperating medium such as compressed air or oil is supplied through the conduit 36 from the control box to the flexible conduits 80, which in turn communicate with a channel or passageway 81 of the block 74 in which is housed a slidably operable plunger' rack member 82. The oil under pressure forces this rack outwardly to rotate a pinion 83 adapted to mesh therewith. This pinion in turn engages with teeth 84 on the member 7 6,.causing it, as the pinion rotates, to'gradually swing downwardly until the springactuated dowel pin 85 coming into engagement' with the opening 86 locks it in a vertical position. As the member 76 moves to a vertical position the end of the plunger rack 82 reaches the passageway 87 opening it, this passageway communicates with both ion y .11uY i the channel 81 and the passageway 88, the" lexible conduit 89 establishing communication between the passage 88 and the plunger end to the member 76 and at the other end to the foot 79. As the plunger 78 moves inwardly the spring-actuated dog 92 engages y the lever. 93 pivotally mounted at 94 causing the end 95 to engage and depress the pin 96, thus releasing the dowel pin 85, 'permtting the member 76. to return to normal 1 and 3, by t '-coil spring 77. Simultane' .ously with the return ofthe jack to normal position the pressure medium will return,l

through the conduit 89,' passageways 88 and horizontal p 'tion, as indicated in Figures 87, to the channel 81. As the member 82 moves inwardly in the channel 81, the port 87 communicating therewith is cut oi. The medium will then flow along passageway 97, forcing the ball 98 upward, which will permit the medium to How to the channel 81 by of the wheels, on the valves for such wheels.

At the same time the operating medium for the brakesl will be automatically released, returning unin- -terruptedly through the unchecked conduits The conduits are provided with check valves 101 to prevent the returning operating medium from the jacks in operation inuehcing the'jacks not in'operation.

Referring now to the modified form as illustrated in Figures 18 and 19, it' will beobserved that provision is lmadeto install our jack and brake operating device on mechanically braked cars in connection with which we provide the lever operatin valves 102 connected through conduits to te pres- From the features of our invention are freely;
